“…In contrast, a number of recent research papers relating to user association have incorporated matching theory as a result of its relatively low level of complexity [31][32][33][34][35]. In [31], the authors presented two frameworks that use auction games and matching theory to facilitate the efficient admission of secondary users into the HetNet.…”

“…The study presented in [32] investigated a matching game for user association and identified a solution that is close to optimal. In [33], the authors presented a pair of many-to-one matching games aimed to achieve optimal association for users in both downlink and uplink scenarios. In [34], the authors propose algorithms for resource allocation in 5G HetNets that are based on stable matching and support many-to-many relationships.…”

The sixth-generation (6G) wireless cellular network integrates several wireless bands and modes with the objectives of improving quality of service (QoS) and increasing network connectivity. The 6G environment includes asymmetrical heterogeneous networks (HetNets) with the intention of making effective use of the available frequencies. However, selecting a suitable gNB and a communication channel that works for users in the network is an enormous challenge in 6G HetNets. This paper investigates a joint user association (UA) and channel allocation (CA) problem in two-tier HetNets by considering the downlink scenario to improve QoS. Our study presents an innovative scheme for user association and channel allocation, wherein the user can be connected to either the macro base station (MBS) or a possible small base station (SBS) in a direct or relay-assisted link. Furthermore, the proposed scheme identifies the optimal channel to be allocated to each user so that the overall network QoS can be maximized. A symmetric matching game-based user association is proposed to find the optimal association for users. Moreover, a modified auction game is applied to allocate the optimal channel by considering the quota of each gNB. Regarding connection probability, throughput, energy efficiency (EE), and spectrum efficiency (SE), the simulation results show that the proposed approach performs well over the state-of-the-art techniques.

“…While authors in [12] used a Boston school mechanism for the uplink user association problem in HetNets. Two many-to-one matching games were proposed in [13] for optimal user association in the uplink and downlink in 5G multiple radio access technology ultra-dense networks. The work in [14] considered the problem of joint user association and channel assignment with proportional fairness signal-to-interference-plus-noise ratio (SINR) based power allocation in downlink multi-cell non-orthogonal multiple access (NOMA) networks.…”

A Two-Stage Matching Game and Repeated Auctions for Users Admission and Channels Allocation in 5G HetNets

The fifth-generation (5G) wireless cellular networks aim to increase the users' capacities and quality of experience as well as to integrate different wireless bands and modes of access. The introduction of cognitive radio technology and heterogeneous networks (HetNets) as part of the architecture of the 5G aims to efficiently reuse the available spectrum. This paper presents a two-stage framework based on matching theory and auction games with the objective of efficiently admitting secondary users to the wireless scene. In the first stage, a fast convergence matching game for the users admission problem in 5G HetNets is considered, where secondary users are associated to appropriate secondary base stations. These base stations access the available primary spectrum on behalf of its associated users in the next stage, namely a repeated modified English auction. Results show the existence of a stable matching point for the users admission game and a Walrasian equilibrium point for the repeated auctions. In addition, extensive simulations are performed to compare the proposed repeated auction against the single auction and the matching theory. It is proven that the repeated auction game outperforms the single auction game and matching game in terms of the occupancy of primary channels and the satisfaction of the secondary users.

“…Resource allocation [30], [31], [32], [33] is considered a key problem to resolve in 5G-IoT networks, especially for network slicing architecture [34]. The latter needs to share independently different resources with several slices offering various services in order to meet the device's QoS requirements.…”

<p>The massive device’s connectivity and the great data traffic demand are growing explosively in our daily lives, especially in the Internet of Things environment. For this purpose, the main objective of operators is to find the most innovative and powerful solution that can support all these needs. The sliced fifth-generation mobile network (sliced 5G) is considered a promising architecture using a new radio access technology called New Radio (NR), which can offer significantly higher data rate experiences. In addition, using Network Slicing (NS) architecture will allow more flexibility and isolation to the predefined infrastructure. The NS isolation effect’s benefit is eliminating inter-slices interference since they will be independent of each other. This paper aims to resolve the user-association problem in a sliced 5G (NR)-IoT network. Hence, the problem is formulated as an Unconstrained-Markov Decision Process (U-MDP) model. Then, the U-MDP association algorithm is proposed to find the optimal association among users and the different slices. Numerical simulation results validate the theoretical proposed model and prove her efficiency in improving the global system performance while respecting all devices’ Quality of Service.</p>
